Hello I just bought a 28mm F1.9 VoigtlanderUltron + Screw-adapted M 28/90mmVoigtlander.j contemplated buying a Jupiter-12, can I use the same adapter on my rd1s? thank you in advance Yann:)
 
I stand to be corrected, but I think the rear element of a Jupiter 12 will foul the shutter on the Epson unless only used for close-ups.
 
Thank you for your reply. I practice just as the digital and film only the enjoyment of photography account.Mandatory debate for or against the pixels and a sterile debate (the invention of the wheel does not prevent people from walking and having fun has this). I must think to use new technologies without forgetting what our old one we left. I understand from when you speak I smell an old selenium cell and you're right the old equipment has a smell particulière.C is one tool factories was a time when everything was less impersonal, sanitized;)
 
Peter said that the bulbous rear element of the J-12 might bump into something in the camera body. I said the same on another thread recently, but someone corrected me and pronounced them compatible.

One, the adapter you use for your Ultron 28 will work with the J-12.

Two, there is perhaps too little difference in angular coverage between 28mm and 35mm to justify owning both focal lengths.

It seems a matter of sample variation; as the lens is calibrated by screwing the rear element in and out, there is some variation in how deep the lens protrudes into the bory. On my Bessa, which has the same shutter as the R-D1, I could use a J-12 unless I'd focus further away than some 3m, in which case the rear element would go in and hit the shutter. When you open the camera from the back, you'd actually see the rear element bumping against the shutter. I think I posted a shot somewhere taken with the combination.

Of course, 3m maximum distance is not a problem with the wideangle, infinity will be covered by depth of field.

The problem is that on the R-D1 you can't see the shutter from behind, so it's a matter of faith. Someone else posted a thread about it here a long time ago, but I'm not sure whether I'd risk it. Saving a little money for a Cosina 35/f2.5 or something is probably worth it.
